This is my first winter with hens. They started laying in the late fall, and haven't let up. I do not give them any more hours of artificial light, yet my brown egg layers lay every day, and my single white layer lays about every other to every three days. I decided not to give them any more light since it's my unde rstanding (after reading threads here) that laying every day and at the same time trying to store energy to stay warm is too hard on hens in the winter. They're all healthy, eating well and the eggs are healthy despite a pretty cold winter here in CT so far. I'm not too worried since they made it this long, but is this normal?
